[FEATURE] Replace legacy Moment.js with Day.js or date-fns to improve performance

[sammy200-ui]

The website currently uses Moment.js for date formatting and manipulation.
But its officially in maintenance mode since September 2020. The maintainers recommend using modern alternatives. ref

It also adds ~60KB (minified) to the bundle and is not tree-shakeable, meaning the entire library is included even when only a few functions are used. ref

I propose migrating to a modern, lightweight alternative like Day.js or date-fns.
Which have estimated 90%+ reduction in date library footprint and aligns with modern ecosystem .

We could use any of the two mentioned cause both are excellent libraries. Would like to discuss before working on with maintainer.

Yes, I am interested in making a pr!!
